Product Model: Yokogawa ADV169-P50

Brand: Yokogawa

Series: ADV169 Series – Digital Input Modules (High-Density, Isolated, Common Minus Side Every 16 Channels)

Product Introduction

The ADV169-P50 is a high-density digital input module developed for industrial automation and control systems, especially suited for distributed control systems (DCS) platforms and I/O rack expansions. It supports 64 discrete input channels within one compact module, grouped so that every set of 16 channels shares a common negative (COM-) connection. This grouping reduces wiring complexity while retaining strong electrical isolation between groups to maintain signal integrity.

The module is capable of capturing both dry-contact signals (such as switches and relays) and low-voltage DC signals, enabling robust field device interface for valves, alarms, pushbuttons, status contacts, and more. It is engineered for demanding environments where signal noise, long wiring runs and dense I/O installations are common. The compact footprint and high channel count make it an effective choice to reduce cabinet and rack space, streamline field wiring and lower total system cost.

As part of the ADV169 series, the ADV169-P50 integrates into Yokogawa’s modular I/O platform, sharing base frames, backplanes, cables and support infrastructure with other modules. The revision “P50” indicates a particular variant tuned for the series’ architecture, providing a balance between cost and performance for typical discrete input needs in process automation.

Technical Specifications

* (Note: Some listings show larger “dimensions” that may reflect packaging or rack insert envelope. Real module width/depth may be smaller.)

Applications

• Large-scale process control systems (chemical, petrochemical, power) where hundreds of discrete status signals must be acquired and monitored.

• Water and wastewater treatment plants, pump stations, valve fields, and utility automation, where many ON/OFF signals from field devices need to be brought into the control system.

• Manufacturing and machine-automation installations with many discrete sensors, limit switches, safety interlocks etc., where high channel density saves cabinet space and wiring.

• I/O rack expansions or retrofits: when upgrading existing control cabinets, the ADV169-P50 allows adding many input points with minimal modules, reducing installation time and cost.

• Environments with challenging signal integrity needs: the isolation between channel groups helps manage electrical noise, ground loops and large wiring runs.

Advantages

• High channel density: 64 input channels in one module reduce the number of modules needed and cut installation space significantly.

• Efficient wiring: By grouping 16 channels per common minus side, wiring complexity is reduced and fewer terminal blocks or commons are needed.

• Robust isolation: Each block of 16 channels is isolated from others, enhancing noise immunity and protecting signals in electrically noisy industrial environments.

• Flexible input type: Accepts dry contacts or low-voltage DC signals, giving installation flexibility for many types of field input devices.

• Compact and lightweight: With an approximate weight of 0.30 kg and moderate size, the module is easy to handle, install and integrate into existing racks or panels.

• Platform compatibility: As part of the ADV169 series, the module works with established base frames, backplanes, cable systems and supports maintenance and spare-parts management in the same ecosystem.

• Cost-effective installation: The combination of high density, simplified wiring and reduced module count leads to lower installation cost and easier system maintenance.

• Reliable long-term performance: Designed for industrial conditions, the module offers dependable performance when installed correctly in standard control-cabinet environments.
